摘要

A one-pot and three-component reaction is described for the preparation of 2,3-disubstituted isoindolin-1-ones. Heating a mixture of 2-formylbenzoic acid, a cyclic six-membered beta-dicarbonyl compound, and a benzylamine under solvent-free conditions afforded the title compounds in good to excellent yields. The generality of the reaction was shown by the use of various beta-dicarbonyl compounds including 1,3-cyclohexadione, dimedone, Meldrum's acid, N,N-dimethylbarbituric acid, and some benzylamine derivatives.
